401 Epoxy Floor Primer is a two pack, water dispersible epoxy based primer/sealer/clear coating, especially formulated to meet the technological and ecological requirements of modern building and industrial practice. Ideal for use as a clear sealer on concrete and masonry surfaces.
401 Epoxy Floor Primer is a two pack, water dispersible epoxy based primer/sealer/clear coating, especially formulated to meet the technological and ecological requirements of modern building and industrial practice.
401 Epoxy Floor Primer can act as a curing membrane to increase hardness of concrete by allowing full hydration of cement and can be applied to new concrete, 7 days after being poured. 401 Epoxy Floor Primer in this circumstance must be left as a standalone sealer or overcoated with 303 Epoxy Floor Paint only.
401 Epoxy Floor Primer is non-flammable and solvent free, is low odour, and may be applied to dry or damp surfaces. 401 Epoxy Floor Primer has excellent adhesion to most building materials, is nontoxic once cured, and consequently is a highly versatile material lending itself to application in many different types of location and circumstances.
For lower temperatures (5°C - 30°C) or when a faster overcoating times are required a Winter Grade version of this product is available - Click Here for the Technical Data Sheet.
This product is for Professional Use Only.

Should a non-slip finish be required, 508 Fine Particle Anti-Slip Additive can be added to the coating during mixing prior to application to produce an even and easily cleanable texture to the dried surface.
Alternatively the 'Anti Slip' option can be selected when purchasing the product and the 250 micron grade of 508 Anti-Slip Additive will be added at 2.4% prior to receipt.

PTV Ratings:
Slip potential classifications from Pendulum Test Values.
Slip Resistance Values | |
---|---|
PTV | Slip Potential |
< 25 | High |
25 - 35 | Moderate |
> 35 | Low |
The above results must only be used as a general guideline as the slip resistance of a cured resin coating can vary considerably due to many factors including: application technique, variations in film thickness, dispersion of the anti-slip texturing additive and the surface variations of the substrate and location to where it will be applied.
To obtain accurate PTV readings that are site specific (if required) it is strongly recommended that a slip assessment pendulum test is undertaken on each specific site after completion of the installation when the resin has fully cured.
A full copy of the official test report is available upon request.
Note: For steel work a coat of 404 Epoxy Metal Primer is recommended as a primer instead of 401 Epoxy Floor Primer.
Note: Substrates with high moisture content or oil contamination can still be coated in most instances by the inclusion of one of our specialist primers. Please see 402 Damp Proof Coating and 403 Oil Tolerant Primer for full details.
Mixing:
Mixing Ratio:
Note: Thinning of the material is not usually necessary. However, it is permissible to thin 401 Epoxy Floor Primer by the addition of up to 20% by volume of clear water. This will reduce the viscosity and facilitate application.

![]() | Question: Is your primer suitable for applying to self-levelling compound prior to painting? I have used Mapei 1210 compound. I would like to either paint the floor or simply seal it to stop staining. Thanks |
Answer from Rawlins’ Technical Team: You would need to speak to Mapei's Technical Department regarding this, you will need to check whether they are happy for this levelling compound to be left as a wearing course and coated with a water based epoxy. If the answer to both is yes, then after suitable preparation our 401 Epoxy Floor Primer could be applied. | |
